The dimly lit space of the Celestial Tower.

A slender figure flickered at great speed, and a rather powerful force spread from his every movement.

And with each of his blows, there will be a thunderous explosion on top of this shadow membrane, which makes the power in his body skyrocket to a new level again!

Syllable!

After the fourth crisp sound was heard, the figure's body trembled obviously, and the muscles of the body contracted like a dragon, and a fierce energy passed through it.

"Ahh

The figure let out a deep roar, then the fist that had stopped in the air suddenly retracted in half, and then burst out again!

Boom!

A rather heavy sound, like the sound of a stone falling to the ground, suddenly raged, stirring the air and rolling, turning into a wind pressure that swept out, and only after a few breaths did it slowly subside.

And this punch seemed to drain all the strength of the figure, and at that moment it fell to the ground a little weakly, his delicate face turned red like a fire, and sweat poured out like a wild waterfall.

"Still won't work......"

Gasping violently, the figure muttered to himself with a rather helpless wry smile on his face.

This figure is undoubtedly Xia Xuan.

It's been a full month since I left the Underground City that day.

In this month's time, Xia Xuan stayed in this mercenary tower and practiced hard except for some necessary time to go out.

After returning to the Mercenary Tower that day, Xia Xuan did not rush to throw all the pills in his hand into the Chaos Pool and enter the cultivation, but instead forcibly forced himself to endure the impulse in his heart and began to heal his wounds cross-legged.

Under the full operation of the Heavenly God Technique, in just two nights, Xia Xuan's body was restored to its original state.

And perhaps because of the continuous battles in the past few days, Xia Xuan also ushered in a breakthrough in the ninefold body of the calciner!

As he broke through the bottleneck of the Nine Layers of the Tempered Body, the Yuan Force Seed in Xia Xuan's Dantian grew by a few points, and at the same time, his physical strength also reached the terrifying 80,000 jin limit, and this kind of terrifying power was several points stronger than some ordinary brute beasts!

And compared to him, the gap in strength of the ordinary Tempered Body Ninefold Peak Martial Artist was even more immeasurable than that of him, a gap of nearly several times!

However, Xia Xuan was not satisfied with this, because he knew that although the physical strength of 80,000 jin in one blow was powerful, it was not the limit of the tempering period!

Some of the lifeable creatures in the world can reach the limit of their strength in the calcining period, which is 100,000 catties!

This is a terrifying number, it is said that only some legendary divine beast cubs can touch such a physical realm, however, under the transformation of the powerful energy of the Heavenly God Jue, Xia Xuan's physical body has begun to get infinitely close to this!

Therefore, in the following days, Xia Xuan began to try to temper his physical body to increase his physical strength. And, in his hands, the Million Heavenly Fist is the best means of tempering the physical body.

The consumption of the Million Heavenly Fist is not huge, but the demand for physical strength and qi and blood is quite terrifying.

The superposition of the power in the body one after another requires the strength of the martial artist's body and the control of the strength to be quite good, otherwise, such a strong force travels through the body, and a bad one will become a deadly bomb!

Prior to this, Xia Xuan had already discovered that every time he used the Million Heavenly Fist, although the strength of his physical body was very subtle, it was indeed steadily increasing.

With the attitude of trying, Xia Xuan began to cultivate the fourth ring of the Million Heavenly Fist. Millions of Heavenly Fists, the more difficult it is to practice in the future, the higher the physical requirements for the martial artist, and the more dangerous it is to practice.

Even Xia Xuan, during a practice, he did not control the power in his body well, resulting in a backlash and vomiting blood, which shocked his internal organs. However, with the terrifying recovery ability of the Celestial Technique, the injury was not a big problem.

And finally seven days later, Xia Xuan successfully broke through the Million Heavenly Fist to the fourth ring, and at the same time, as he expected, after the breakthrough of the Million Heavenly Fist, his physical strength also successfully reached the limit of 90,000 catties!

This is a terrifying increase, compared to seven days ago, Xia Xuan at this time is really much stronger.

At this moment, Xia Xuan had absolute confidence that if he fought to the death with Blood Shura again.

This time, I'm afraid he doesn't need to use the Explosive Yuan Seal at all, just the 90,000 jin of terrifying power combined with the Four Rings of the Million Heavenly Fist is enough to blast it into powder, even if it has a fifth-order combat skill like the Blood Parasitic Armor, the result will not change at all!

And, after successfully verifying that the Million Heavenly Fist was indeed able to break through his physical strength, Xia Xuan became even more crazy in his cultivation.

In the next dozens of days, Xia Xuan was immersed in the cultivation of the Million Heavenly Fist almost all the time, and every time he practiced until his physical body was out of strength, he immediately crossed his knees and recovered.

It was an almost inhuman torture, but he persevered. And the strength of the physical body and the yuan force in the body are also making steady progress under such a decline and rise.

However, the fifth realm of this Million Heavenly Fist was unable to break through for a long time.

At this time, although Xia Xuan was able to barely use the fifth ring, because his power accumulation was not perfect, the sound that caused the eruption was quite dull, not as crisp as the first four rings, and the consumption of the physical body was also quite huge and terrifying.

Under this imperfect Five Rings Million Heavenly Fist, Xia Xuan used it once, and he would feel the muscles in his body lose strength, and he had to enter a state of pranayama to recover.

"What the hell is going on with this fifth ring, I obviously have a perfect control over the accumulation of power, but why do I always feel like I can't burst out with all my strength at the end. ”

After gasping for two breaths violently again, the flush on Xia Xuan's face slowly subsided, and he muttered with a wry smile.

After so many days of unsuccessful cultivation, maybe he still missed some important details......

The thought flashed in his heart, Xia Xuan sat cross-legged, and with a wave of his hand, a martial arts light and shadow emerged from the void again, and immediately, his gaze also fell quite solemnly.

When the light and shadow appeared, the posture was instantly opened, and the fist strength roared like a wind, and it was the Million Heavenly Fist that was used!

Bang Bang Bang ......

The light and shadow of the martial arts flickered, and the first four rings were almost instantaneous, and as the fourth sound fell, Xia Xuan's gaze also slowly solemnized and gathered, and his gaze fell on him instantly, not wanting to let go of the slightest detail.

And, as if to cater to Xia Xuan's thoughts, the extremely fast flashing movements of Martial Arts Light and Shadow also slowed down.

The punch was slowed down countless times, like a snail crawling, but the force on it showed no signs of dissipating, but became more and more concentrated and terrifying!

Syllable!

In the end, when the power gathered to the very peak, a sound that was even more deafening than the previous four explosions suddenly came out, and this sound was like thunder on the ground, which made Xia Xuan's pupils suddenly light up in an instant!

"This fifth ring...... Is it ......?!"

Xia Xuan seemed to have noticed something that he had missed without paying attention to before. However, at this time, he was not completely sure.

Exhaled lightly, and immediately, Xia Xuan waited for the martial arts light and shadow to hit all the ten rings, and then when he started from the beginning again, his eyes condensed again.

As the first four explosions sounded, Xia Xuan's eyes were also completely concentrated to the extreme, everything around him seemed to have disappeared, and at this moment, in his eyes, only the extremely fast dancing movements of martial arts light and shadow remained.

Immediately, Xia Xuan saw that between the punches of Martial Arts Light and Shadow, and between the muscle contractions, his arm was trembling slightly in an almost invisible arc, and it was such a small detail that made Xia Xuan's eyes suddenly brighten!

"It turns out that the trick to the fifth ring of the Million Heavenly Fist is here!"

Xia Xuan's face swelled with a look of ecstasy, and he exclaimed, and then he didn't hesitate, he directly formed the seal knot of cultivation, and immediately resumed pranayama.

How to break through the fifth ring of the Million Heavenly Fist?

This problem has trapped Xia Xuan in place for more than ten days, and now, he has finally found a breakthrough!
